In this tutorial we will see two ways for changing the default wallpaper of your login screen under Ubuntu 12.10 (Quantal Quetzal). Changing the background image of the logon screen will make it more attractive and meet your taste.

First of all, I want to let you know that I have tried to change the logon screen with Ubuntu Tweak
under Ubuntu 12.10, but unfortunately it didn't work due to a bug. The
author of Ubuntu Tweak has promised that it will be fixed in the next
version of the software. The methods given below are also workable on
Ubuntu 12.04 Precise Pangolin.

Method 1

Open the terminal and access the /usr/share/backgrounds/ folder with this command:

gksu nautilus /usr/share/backgrounds/

Place now the wallpaper you want to use in this folder:

Then right-click on an empty space on your desktop and select "Change Desktop Background". In the Appearance window, select "Picture Folder" from the dropdown menu and select the wallpaper you have placed in the /usr/share/backgrounds/ folder:

Log out now to test the login screen. The only drawback with this method
is that you can't set a different wallpaper for both desktop and logon
screen.

Method 2 (Recommended)

Start the terminal and run this command to get root privileges:

sudo -i

Allow now lightdm to establish a connection with the Xserver with this command:

xhost +SI:localuser:lightdm

Sign in now as lightdm:

su lightdm -s /bin/bash

Disable now "draw-user-backgrounds" and "draw-grid" with these commands:

As you know, it remains three days until the final release of the stable version of Ubuntu 12.10 (Quantal Quetzal) which
will bring more new features and improvements compared to previous
releases. In this article, we will try to give some basic tips that you
need to perform after installing Ubuntu 12.10. If you think that we
missed something useful in this article, you can mention it below
(comment form).1. Change Repsoitory Server Location

It's recommended that you configure Ubuntu to download, update, or
upgrade packages from the main server rather than using location-based
servers. You can do this as follows:

- Run this command:

sudo software-properties-gtk

- Set now this option under the "Ubuntu Software" tab:

Download from: Main server

- In the "Other Software" tab, make sure these options are selected:

* Canonical Partners* Canonical Partners (Source Code)

- Close the window and run an update with this command:

sudo apt-get update

2. Update/Install Device Drivers

In Ubuntu 12.10, jockey-gtk has been superseded by software-properties for managing third-party driver configuration. So, to access this feature, open the terminal and run this command:

sudo software-properties-gtk

Open now the "Additional Drivers" tab, then install any detected driver for your keyboard, wireless cards, graphics cards, etc.

For Nvidia graphics cards, it is recommended that you use Nvidia proprietary drivers instead of Nouveau to
be able to get better graphics performance in games, HD videos and so
on. You can install the latest Nvida driver using the x-swat PPA
(stable) with the following commands:
